# Every hour over the retainer reaches the invoice

You see how much of the package each client has used, which invoices go out on the first of the month and which clients are late with payment.

Hours are logged with a timer from the task, the certificate is built from hours, and the retainer fee is invoiced on schedule by itself.

**In short.** Krokul is a B2B CRM for companies that serve clients on retainers and sell time: hours are logged with a timer from a task against the client’s package, overage is shown with its price before the invoice, the completion certificate is built from hours, retainer invoices go out on a schedule, debts are visible by due date with a payment promise, and revenue minus the cost of hours gives the margin of every client.

**Who it’s for:** outsourced accounting and legal; consulting; agencies; IT services and support.

## Sound familiar?

In companies that sell time, part of the work done stays stuck in the hours — 4.5% of revenue on average (SPI Research, Professional Services Maturity Benchmark, 2026).

- «The client asks for more than the retainer covers, and that work stays off the invoice»
- «Hours sit in a time tracker, and at month-end you still have to build a report and an invoice»
- «On the first of the month someone sits down and issues the retainer invoices by hand»
- «We remind clients about last month’s payment by phone»
- «Client tasks live in people’s heads and in messengers»

## Over the retainer, priced before the invoice

How much the client has used and how much goes over the package — in their card, with the amount to bill.

## Certificate from hours

The package and the hours over it in one certificate, with the invoice built from it. By month-end the document is ready.

## Retainer fees bill themselves

A subscription contract with a period creates an invoice every month — on the first the invoices are already there.

## Who owes and when they promised to pay

Debts by due date and a payment promise with a date — you see whom to remind today.

## Hours by timer from a task

Client tasks live in the CRM, hours from them are logged to the client and the project; everyone sees their own.

## Which clients are profitable

Revenue minus the cost of hours — the margin of every client as one number.

## Tickets with a response deadline

Priority, owner and deadline — you can see what’s urgent.

## Questions and answers

### How much does it cost for a team of 8?

Users do not affect the price: 8 people cost the same as one. Scheduled retainer billing and debtors are on the Money plan, $149 per month; projects, hours and certificates are on the Margin plan, $399 per month. Hours don’t count as transactions.

### Do I need an implementation partner to get started?

You can start on your own: the demo company and your own company are both launched from one question about your business type. A certified Krokul partner can take on data migration, accounting integration or complex rules.

### Who sees the rate and margin?

Those whose role allows it. A team member sees their own tasks and hours; the rate, cost and margin are visible to roles with access. The server checks permissions on every request.

### How are monthly invoices issued?

You sign a subscription contract with the client with an amount and a period. An invoice for each period is created on the contract’s schedule by itself.

### What if the client used more hours than the package?

Hours over the package are shown in the client and project cards along with the amount to bill, before the invoice. The completion certificate includes both the package hours and the hours over it.

### Is there a timesheet and a rate for each employee?

Hours are calculated at a single team rate, which keeps a history of changes. A working-time timesheet and a separate rate per employee stay outside Krokul.
